Introduction

HTML is often used to extract data from a web page.

The HTML form has a variety of components, including:

Choose
input option
label
fieldset
outgroup
textarea and so on.

It also has many qualities that any of its sub-elements might possess.

These qualities include, for instance:

target method
action autocomplete
among other things.

Together, they enable us to collect data from visitors to our website seamlessly.

What does the HTML <select> element represent?

This element finds use in several ways. It asks users to choose what they want from a list of possibilities.

The <select> tag uses the <option> element to provide the user with options. The problem is that the tag is shown on the site using the first choice by default.

<!DOCTYPE html>

<html>

  <head>

    <title>

     Choosing the default setting in the<select> element

  </title>

</head>

  <body>

    <select name="scheme" id="scheme">

  <!-- This is where we set the value to be displayed-->

        <option value="none" selected disabled hidden>

          Select an Option

      </option>

        <option value="free">Free</option>

        <option value=" beginning "> beginning </option>

        <option value=" expert "> Expert</option>

        <option value=" business "> Business</option>

    </select>

</body>

</html>

A common use of <select> may be seen in the example above. It is assigned a name property that indicates the name of the related data point transmitted to the server and an id attribute that allows it to be connected with a <label> for accessibility purposes. A <option> element within a <select> defines each menu item.

When a particular choice is made, the value property of each <option> element should include the data value to transmit to the server. The text within the element is used as the default value in the absence of a value property. An <option> element may apply its chosen property, which loads with the option selected by default.

You may customize the <select> element with certain unique properties, such as size, which indicates how many choices should be presented at once, and multiple, which indicates if multiple alternatives can be picked. Additionally, it supports the most common form input properties, including autofocus, disabled, and required.

It is possible to build distinct groups of choices inside the dropdown by nesting <option> elements within <optgroup> elements. To make separators that visually divide up your alternatives, you may also employ <hr> components.

Add a div element in HTML first, then give it the class name "content" In this component:

Add the element <h1> to the header.
After that, insert some material into the <p> element. Use the <strong> element within the <p> element for bolding text.
Give the attribute name and ID to the HTML "<select>" element.
The choices in the dropdown menu are shown in the chosen element, as we have already covered. These choices are supplied using the HTML "<option>" element.

Features

Included in this element are the global properties.

1. Automatic

This is a hint string for a user agent's autocomplete function. For information on utilizing autocomplete and a comprehensive list of values, see the HTML autocomplete attribute.

2. Focus automatically

When the page loads, you may use this Boolean property to choose which form control should receive input focus. The autofocus property is limited to one form element per page.

3. Impeded

This boolean property indicates the inability of the user to interact with the control. If this property is left empty, the control takes its value from the enclosing element (e.g., <fieldset>); if the control is enabled, then there isn't a contained element with the disabled attribute set.

4. Shape

The <form> element that the <select> should be associated with (its form owner). This attribute's value has to be a <form>'s ID from the same document. (The <select> is linked to its predecessor <form> element, if any, of this property is left unset.)

You may correlate <select> elements with <form>s anywhere on the page, not just within <form>s, thanks to this property. Additionally, a descendant <form> element may be overridden.

5. Numerous

This boolean property shows that the list allows for the selection of numerous alternatives. One choice may be chosen at a time if it is left unspecified. A single-line dropdown will not appear in most browsers when many are provided; instead, a scrolling list box will.

6. Appellation

The name of the control is specified using this property.

7. Needed

A Boolean property that signifies the need to choose an option with a string value that isn't empty.

8. Proportions

This property indicates the number of rows in the list that should be viewable once if the control is displayed as a scrolling list box (for example, when many are required). Browsers do not need to display a chosen element as a scrolling list box. Zero is the default value.

The selected="selected" property may be used to specify the default value for an HTML <select>

The selected="selected" option in HTML code may be used to set the default value. In the <option> element, we write the chosen attribute. The selected option may be chosen by default when the web page loads if the selected attribute value is set to selected. The boolean attribute in HTML is what it's known as. First, in the dropdown list, the item that has been pre-selected will appear. Just the <option> element is eligible to utilize this property. Google Chrome, Internet Explorer, Firefox, Opera, and web browsers are supported.

Make a <select> element with five choices inside, for instance, the HTML body. For the value attribute of each option, write the digits 1 through 5. Write the text from one to five between each choice's <option> tags. Next, write the chosen attribute with the value selected immediately after opening the <option> element in the specific value (option 3 in the example below) you want to set as the default. The <select> tag should then be closed.

To choose the default value in a dropdown list, the example below uses the select=selected technique. To pick values between one and five, we developed a dropdown list. Using the chosen property to designate the element as default, option Three loads by default when the page reloads.

<body>

    <select>

        <option  value="1">One</option>

        <option  value="2">Two</option>

        <option  selected="selected"  value="3">Three</option>

        <option  value="4">Four</option>

        <option  value="5">Five</option>

    </select>

</body>

Style “content” div

v.content {

     width: 470px;

     height: 480px;

     border: 2px solid #824C62;

     margin: auto;

     background-color: rgb(64, 32, 32);

     padding: 16px;

     border-radius: 4px;

}

Properties

Name	Type	Description
el	Element	The first DOM element used by the plugin.
options	Object	The alternatives were used to initialize the instance.
isMultiple	Boolean	Should this be a multiple-selection
wrapper	Element	The element with the select wrapper.
dropdown options	Element	UL element that can be dropped down.
input	Element	Enter text to display the option that is now chosen.
dropdown	Dropdown	An instance of this select's dropdown plugin.

When accessing the HTML div element with the class content, use the ".content" protocol. These are the listed CSS attributes with an explanation, in order of the above:

Its "width" attribute modifies the element's width.
The elevation of the element is determined by its "height" attribute.
The "border" attribute specifies the boundary surrounding the element. The worth of
provides information about the border's color, style, and width.
The "margin" attribute describes the circle's circumference.
The color of the element's background is specified by "background color."
To make the area around the element's content larger, "padding" is used.
What gives the element its rounded edges is its "border-radius" attribute.

Users of keyboards may choose several adjacent things by:

Concentrating on the <select> element (for example, by using Tab).
Using the Up and Down cursor keys to go up and down the possibilities, they may choose an item at the top or bottom of the range they wish to choose.
Increasing or decreasing the range of objects chosen is done by holding down the Shift key and using the Up and Down cursor keys.

Users of keyboards may choose several non-contiguous objects by:

Concentrating on the <select> element (for example, by using Tab).
To adjust the "focused" option—the one that will be picked if you so choose—hold down the Ctrl key and move the mouse up and down. Like a keyboard-focused link, the "focused" choose option is shown with a dotted outline.
To choose or deselect "focused" pick choices, press Space.

Example

<select id="element">

     <option>option 1</option>

     <option>option 2</option>

     <option>option 3</option>

     <option>option 4</option>

   </select>

  <script>

    document.getElementById("element").selectedIndex = 2;

  </script>

Regulations

1. prerequisites

The element must be selected for select() to function. It must be chained from a command that returns DOM element(s).

2. Accusations

select() will automatically retry until all chained assertions have passed, waiting for the element to achieve an actionable state.

3. Timeouts

select() may run out of time while waiting for the element to enter an actionable state or while it waits for additional assertions you've added to pass.

Conclusion

Many menus are selectable inside the HTML element. These menus are given within the HTML element. For an HTML element, the property "selected" for that option must be specified to establish the default value. , this study has explained the HTML element and how to change its default value.

Notably, in addition to being chosen, hidden and disabled are also included in the code above to allow us to show personalized messages that the user cannot view as alternatives.
