I tried to add extra constraints to a livetable with the extraParams option but it is not working like I would expect it. If I use equal sign(=) as operand, it works just fine, but any other operand like not equal(I tried !=, ~=, <>, <, >, in) is not working. Is it just possible to use equal as operand?
Also one column in my livetable is the type list. And I tried also to just get Elemnts which have a string in this list with the oprand in in extraParams and it did not work. Then I read about the method with JSON. But the issue is, the livetable is included in a page which is used as template and should display all elements, which have the parent page name in the mentioned list, so the search has to be adopted every time and I have to edit the JSON page. I thought about that I could always change the content of the file but now I have the issue with quotation marks, because the text I want to write to the file contains these " and these ’ quotation marks and I dont know how get this in one string. Can you please help me ? Thanks a lot!
