Use case: MANY. One example: When you want to display two or more inputs together for the purpose of collecting information for audits or inspections. ie> Criteria 1 “Is the equipment operational?” Answer via a select input: Yes or No. Add image via an image picker and add comments via a text input. In total 3 inputs for criteria 1. Now let´s get to criteria 2 “Has the equipment been cleaned?” Answer via a select input: Yes or No. Add a criteria 2 image via a 2nd image picker and comments via a 2nd text input. And so on… for as many criteria your checklist has.
The above would require for you to group the first three inputs of a criteria question of type “choice” in the dB … and this group´s corresponding visibility set to “sometimes” when a dB entry (a collection record) is of type “choice” as an example. The next set of inputs can be set for a different type of question of your audit or inspection form that requires a different set of inputs … and so on. This would enable dynamically to build different types of checklists into an Adalo app.
