[Free] Custom ListView - ColinTreeListView


Ahh, my mistake, i forgot to implement the ExtraButtonEnabled. :joy:
But it is weird if everything is not visible and there is still a circle.


by the way: I really like it, that by setting the extra.button.width to zero, the text and subtext automatically take all the space of the element! :hugs:


Sure! I didn’t thought about setting the size to zero!

It’s the best free extension !!:wink::wink:


Sir is it possible to add extra text box in listview


It is not required by every one, it should be a part of customizing.


Hello there,

I would like to share a autocomplete textbox (thunkable+ColinTreeListView+TaifunTextbox)

Taifun has made a really nice autocomplete textbox extension, too, which has floating suggestions. This version here has not this nice floating, but therefore can delete entries by using the new extrabutton:

TestAutocomplete.aia (62.0 KB)

Have fun with it!


Superbbbbb thanks

  • Update on 2018.3.4 (Version 8)
    • Fixed extraButtonEnabled not implemented
    • Added support of direct(static) functions in ColinTreeListViewElement
