Thank you for the suggestion.
That Google advanced is implemented using the %input parameter. You're free to add more functionality, but the advanced search parameters are different for each engine, so adding a universal advanced search template is not feasible.

Here is the example usage for %input:
%input{Please select your cup/rare/excellent/So big,A/B/C}
Please select your cup is the title.
rare/excellent/So big are the titles of first, second, third drop-down boxes.
A/B/C are the values of the drop-down boxes.

You can insert %input at any position to use it.
For example, https://xxx.com?abc=%input{Please select your cup/rare/excellent/So big,A/B/C}&xyz=1, after you click it, you will get a popup and https://xxx.com?abc=A&xyz=1 when you selected rare.
