Ah i thought you want to do something on the server side only.
In your case you will need to use GET vars then and don’t really need a form/submit.
- In App Conenct create a variable for each of the filter you want to apply on clicking the button.
- In Server Connect create a GET variable for each of the filters
- On the page, in the App Structure bind variable values to the server connect GET variables.
- Select the button, add new dynamic event - on click -> select your variable(s) and select Set Value. Use the values of the inputs.
So when the button is clicked, the input values are assigned as variable values and this reloads the server action with the filters applied.
