How to add a title to a html select tag

Solution 1:

<select>
    <option selected disabled>Choose one</option>
    <option value="sydney">Sydney</option>
    <option value="melbourne">Melbourne</option>
    <option value="cromwell">Cromwell</option>
    <option value="queenstown">Queenstown</option>
</select>

Using selected and disabled will make "Choose one" be the default selected value, but also make it impossible for the user to actually select the item, like so:

Solution 2:

<select>
    <optgroup label = "Choose One">
    <option value ="sydney">Sydney</option>
    <option value ="melbourne">Melbourne</option>
    <option value ="cromwell">Cromwell</option>
    <option value ="queenstown">Queenstown</option>
    </optgroup>
</select>

Solution 3:

You can combine it with selected and hidden

<select class="dropdown" style="width: 150px; height: 26px">
        <option selected hidden>What is your name?</option>
        <option value="michel">Michel</option>
        <option value="thiago">Thiago</option>
        <option value="Jonson">Jonson</option>
</select>

Your dropdown title will be selected and cannot chose by the user.

Solution 4:

You can use the following

<select data-hai="whatup">
      <option label="Select your city">Select your city</option>
      <option value="sydney">Sydney</option>
      <option value="melbourne">Melbourne</option>
      <option value="cromwell">Cromwell</option>
      <option value="queenstown">Queenstown</option>
</select>
