How to select multiple value in dropdown without checkboxes?

Hoping this help:

<select size="1" name="D1">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">c</option>
</select>

The point of a dropbox (<select>) is that the user can only select 1 item/option. You could try making some custom JavaScript & CSS dropbox that records items you've clicked on.

Precisely! Then hold the control button on your keyboard to select as many as you want. If you care to keep the code up to date use:

<select name="somename" multiple="multiple">

And, if I'm not mistaken, you need to add an empty set of brackets to the name of the select:

<select name="somename[]" multiple="multiple">

Without the brackets you will only get the value of the last selected option. The brackets force the value to be an array, which can be accessed by:

foreach($_POST['somename'] as $val) {
print $val;
}
