How to create a button on a catalog item

[Eckhard]

Dear SN community,

I am new to the team to build up our catalog items for our service catalog.
I have an item with a few input fields and dropdown boxes, but I want to have a button included.
When the button is pressed I want to trigger a serverside "Ajax script include" and then fill an input field with a value that gets returned from the AJAX-Call.
But how can I create a simple button and trigger an action in such a catalog item. I can not find a variable type in the list that souds like button or widget.
There is nothing similar.

I found many articles on google that describe that there should be a "macro" variable type, but I do not have this.

Many thanks

Best regards

Eckhard

You can create a variable with type custom there you get options to include macro

Many thanks,
this means that I have to create my own macro with my button and the action right?
Is there a kind of doumentation, because in such a macro many things need to be done like XML and controller. I haven´t expected that a simple button is that complicated.
But I will try, but maybe you have idea if there is kind of documentation / 1st steps for that.

Many thanks
