Hi everyone, I’m trying to customize the stack of my kanban by the variable “visible” that is a boolean ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/1/1273ec42962eaf0d5a78697ef9c6dfda28a01470.png) For some reason having it like this always shows only one column, not both, the other one looks empty ![image](https://us1.discourse-cdn.com/flex016/uploads/weweb/original/2X/8/8cf15aa943a7e7797f620289faf9bbb744cfeb3f.png) If I switch the order then the visible one go to the right column and the first one is empty. ---

Use true and false as strings in your array. “true” and “false”. That might work. Or you’ll need to have the data in string? I’m not sure, but I know there is a thread where I discussed this same issue with numbers on the forum. ---

I saw it! Thank you for that, but the weird thing is that I changed to integer instead of true false, being 0 true and 1 false. And I have the same result, one of the 2 lists is empty. ---

Have you tried the string workaround? ---

I tried it but didn’t have luck. ---

I think you’ve caught a bug, I can see it in the code. Falsy value for the stack fallback to an empty string. So the value expected for the False stack is an empty string inside visible. I will correct it! But if you did stringify your values it should have worked, I guess you forgot to do it both in your stack and data binding. ---

Yup, that’s what I meant, convert it to strings. You could do this with copilot also, via a formula. Should be quick. ---

I tried using stringify but still not working. ---

I think they fixed this in the latest update actually. ---

It should works with your boolean true/false now 🙂 ---

Is working now! Thank you
