Is it possible for the options of an HTML select element to include HTML tags?
For example, given the following code:
<select> <option value="one"><b>one is bold</b></option> <option value="two">two has some <span style='color:red;'>red</span> text</option> <option value="three">three is just normal</option> </select>
No, you can't do this.
<option> tags cannot contain any other tags.
No, but this: Styling HTML Select may help you and there a lof of detail and votes here:
No, you cannot.
What you would do if you wanted this is use something like a floating div and position and display it using Css to look like a select. Then using javascipt clicks allow users to select.
Something like this: Reinventing the dropdown
option tag does not allow any children other than text
Here is a fiddle I created a few months ago that replaces a select element with a list dropdown, and updates the select for each selection made. Just hide select with css http://jsfiddle.net/6zcRk/
The user in this thread then turned it into a plugin available on github( see link in thread)
