Thank you for you answer!
I did a quick search and found this topic:
I understand the principle and it looks like Defold can handle it by default.
“This practice is not necessary in Defold. It’s automatically done for you.”
But in my case (option 2), I wouldn’t have a high number of “item lists” so this is not my core issue.
I’m pretty sure (and I hope) that I’m not the first one to create a screen with a “category selection” menu containing buttons (1 per category) that I click to “contextually” display such or such items (based on the selected category).
How do people design/create these “item lists” in Defold? (with Druid or not - not sure my question was really Druid-specific… Maybe there are more generic best practices)
