Utilizing the Symfony2 FormBuilder, I have an entity field with a choice list that appears quite lengthy. To enhance user experience, I am looking to add CSS for indenting items based on their groups. While jQuery can assist in adding classes based on option values, I prefer setting CSS classes directly within the form's class attribute. Is there a way to set a class for each individual option rather than applying it to all options?
I am considering adding a field in the entity containing the CSS class and incorporating it as an attribute in the formbuilder. My goal is to render HTML where each option includes a unique class corresponding to its value:
<option value="100" class="100">A</option>
<option value="105" class="100">B</option>
<option value="110" class="100">C</option>
<option value="200" class="200">D</option>
<option value="504" class="500">N</option>
While I initially planned on using jQuery to dynamically assign class attributes, I feel it may be better practice to handle this functionality within the formbuilder itself. However, the challenge lies in ensuring that the class changes based on each option's value to facilitate visual identification of item groupings within the dropdown menu.
