Is there no "of" component in MIT app inventor?

[Johane_Aroneore]

Sorry for bad English, its not my first language.

I'm pretty new to this type of coding using blocks because of school, and I'm curious is there an "of" component to get the items of one kind like checkboxes from a component, check image for more info.

as you can see I'm trying to get every checkbox from an arrangement as an easier way to select them rather listing them one by one, is there an easier way for this?

Hello,

you have the "Any component" blocks...and the list with all the checkBoxes:

EDIT_ also you can make a list of the checkboxes of the arrangement to check i f the textBox is in that arrangement:

every block will give you a list of same type component in this screen.

if you want to get a list from a container (arrangement), you can try an extension:
