Option tag is the most useful element in the HTML, which is used within the dropdown list to select specific user preference from the selection list. At a time, one user can select one or more options from the given list. This is the main benefit of option tags in HTML. Wherever the user is going to call datalist through scripts or going to send data to the server, then is a tag used to create datalist.

With the help of CSS, we can give effects to our selection list, able to set positions like a relative, absolute, etc., able to set width and do many other functions. The position for the drop-down list is defined into two values, position relative who is used to display the content of the list exactly right below the select list button. With the help of position: absolute;

Example:

This will restrict the user to select a single option from the selection list.

<select name="State">
<option value="MH">Maharashtra</option>
<option value="GJ"> Gujarat </option>
<option value="MP"> Madhya Pradesh </option>
<option value="RJ">Rajasthan </option>
<option value="AP">Andhra Pradesh </option>
</select>

Similarly, as we all know that we can also select multiple options as per choice into the selection list.

Syntax:

<select multiple>
<option value=""> option1 </option>
<option value=""> option2 </option>
<option value=""> option3 </option>
<option value=""> option4 </option>
</select>

An example for the same syntax is as follows:

<select name="laptops" multiple>
<option value="hp">HP</option>
<option value="dell">Dell</option>
<option value="lv">Lenovo</option>
<option value="sony">Sony </option>
</select>

Attributes of Option Tag in HTML

disabled: This attribute used by setting Boolean value in the forms of true and false. If it is set to true, then the option from the list will be disabled; otherwise, it is false.
label: Suppose we want to give some text as a label, then it’s possible into the option tag. It will consider as a value to that element.
selected: In the web page designing, some cases come where we want to show the option as already selected in the display view. So by setting attributes selected to the options, one can show selected options in the list. One can show only one selected item from the list.
value: one can also be able to set the value to the option in the selection list.
