Hello @likocorp
There are some issues in your style definition.
First, the cff-dropdown-field is a class name, so, so it requires a dot sign in front: .cff-dropdown-field
Second, the element that encapsulate the form has assigned the id fbuilder, so, the correct would be: #fbuilder .cff-dropdown-field
Third, the classes are assigned to the fields containers, and a field is composed by different elements: the label tag (with the label’s text), the entry tag (in the case of a DropDown control a select tag), and a span tag with the instructions for users.
So, if you want to apply the style to the select tag in the DropDown control the correct style definition would be:
#fbuilder .cff-dropdown-field select{
height:30px !important;
}
Note that the select component is not using the dot or sharp signs in front, it is because it is a tag’s name.
Best regards.
