Tips on making a dropdown select menu expand in a downward direction

I'm currently using a select element to choose options from a dropdown list, but because of the large number of items, the list displays in an upward direction instead of downwards. I am working with Bootstrap.

I have reviewed other code samples without success.

 <div class="select-style" style="display: inline-block;">
        <select id="year">
            <option value="hide">-- Year --</option>
            <option value="2010">2010</option>
            <option value="2011">2011</option>
            <option value="2012">2012</option>
            <option value="2013">2013</option>
            <option value="2014">2014</option>
            <option value="2015">2015</option>
            <option value="201">2011</option>
            <option value="2015">2015</option>
            <option value="201">2011</option>
            <option value="202">2012</option>
            <option value="203">2013</option>
            <option value="204">2014</option>
            <option value="205">2015</option>
            <option value="202">2012</option>
            <option value="203">2013</option>
            <option value="204">2014</option>
            <option value="205">2015</option>
        </select>
      </div>

When there are many options in the menu, this selection moves upwards instead of downwards. My objective is for it to display in a downward manner.

Answer №1

If you want to create a dropdown menu with multiple options, consider using the 

<select id="year" size="5">
element. This can be styled further using CSS to adjust the height as needed.

Answer №2

Utilizing CSS for styling is a great option

CSS:

#year {
 width:150px;   
}

To adjust the width of the option, you can include this in your css:

#year option{
  width:150px;   
}

Answer №3

If you're looking for a solution that will make the select options expand downwards and allow you to set the height, I have just what you need. Check out the demo on JSFiddle.

$(function(){
    $('select').chosen({width: '100px'});
    
    $('ul.chosen-results').css('min-height', '100px');
    $('ul.chosen-results').css('max-height', '100px');
});
<select>
  <option value='1'>2010</option>
  <option value='2'>2011</option>
  <option value='1'>2012</option>
  <option value='2'>2013</option>
  <option value='1'>2014</option>
  <option value='2'>2015</option>
  <option value='1'>2016</option>
  <option value='2'>2017</option>
  <option value='1'>2018</option>
  <option value='2'>2019</option>
</select>

Answer №4

To make an element move downward, try setting the offset attribute to a negative number. (This worked for me when using material tailwind components)

<select id="year" offset={-50}>
<option value="hide">-- Year --</option>
<option value="2010">2010</option>
<option value="2011">2011</option>
<option value="2012">2012</option>
<option value="2013">2013</option>
<option value="2014">2014</option>
<option value="2015">2015</option>
<option value="201">2011</option>
<option value="2015">2015</option>
<option value="201">2011</option>
<option value="202">2012</option>
<option value="203">2013</option>
<option value="204">2014</option>
<option value="205">2015</option>
<option value="202">2012</option>
<option value="203">2013</option>
<option value="204">2014</option>
<option value="205">2015</option>
</select>

Simply add data-dropup-auto="false" to your code

For instance:

<div class="select-style" data-dropup-auto="false" style="display: inline-block;">
    <select id="year">
        <option value="hide">-- Year --</option>
        <option value="2010">2010</option>
        <option value="2011">2011</option>
        <option value="2012">2012</option>
        <option value="2013">2013</option>
        <option value="2014">2014</option>
        <option value="2015">2015</option>
        <option value="201">2011</option>
        <option value="2015">2015</option>
        <option value="201">2011</option>
        <option value="202">2012</option>
        <option value="203">2013</option>
        <option value="204">2014</option>
        <option value="205">2015</option>
        <option value="202">2012</option>
        <option value="203">2013</option>
        <option value="204">2014</option>
        <option value="205">2015</option>
    </select>
  </div>
