I haven’t found something usefull so I ask.
I have two type of content. How to propose their content filtered on the creator in one dropdown list so the user can select one.
The goal is to provide a new type of content and link one element from the two others to this one.
not sure I understand exactly what you mean.
For dropdowns you can make them content type text or number and then you could merge 2 lists eg like below but only show the text in the dropdown.
If you want to show restaurants and comments but be able to select a restaurant one time and a comment another time, it is better to add a new datatype though called e.g. restocomment that has a field restaurant and a field comment.
If this does not solve your problem, just pm me, happy to get on a quick call to help you.
It has four different data types in one search…however it is not a drop down element, it is a repeating group ( well 4 ) using an input for search…probably not exactly what you’re looking to create but you could side step the search input and just use a “button” to open the results
