There is a docked panel with two columns. I need to give users possibility to choose what content will be visible in which column.
There will be probably 7-8 different content types. My first thought were two dropdown lists in each column (which is not that bad idea). There could be also a Tab solution, but in this scenario we would have to duplicate each tab for both columns. My last idea was something button-like, but it might be a bit confusing.
Navigation above the columns could have buttons for every content type. Clicking a left or right side of the button would activate content in particular column and highlight a left/right bar on the button. The button could have additional icons and be split by two by a dashed line etc. The con is it's something new to users and they didn't got used to id, so might be difficult at first.
Does anybody have other ideas how to approach this? Actually I think, dropdowns might be still the best (and simple! (kiss)) solution.
