I need to create a "select" type field with some options and when one option is selected, another "select" type field shows up (or its populated) with values that are only displayed with that first option were selected.
Example:
"Select 1" has Shoes and T-Shirts as values
If Shoes is selected, "Select 2" is populated with values 9, 10 and 11
If T-shirts is selected, "Select 2" is populated with values white, black and blue
How can I do that on Contact Form 7
