Trello – How to switch to Condensed List view using Trello on iPad

They should be given the same max height, i.e. they should be the same length if they would otherwise go off the board. If not, it's a bug.

There's a known bug that you may be experiencing. If you are zoomed out and click the 'Add card', then click off, it can shorten the list.

Most of this weirdness will go away with the new card composer, though. https://trello.com/c/pRlmLRWS

I can't tell for sure if you're using the Trello website or the the Trello iPhone app, though I'm assuming it's the web site, given the context.

I recommend you use the app, however. It allows you to tap and drag cards left and right, to different lists, and that works well.

Note that when you click on a card to open it, you can click on the list name, to open up a couple of spinners, to move to a different list, and a different position. However, in my experience, that bit of the user interface is annoyingly buggy, and I gave up using it.

(I just tried it again, and in one of my three attempts, the item I was moving disappeared completely!)
