I have all my tools stored in TitlePanes within a ContentPane as a side panel so the users can have more than one set of tools open at a time. I have my geocoder in a titlePane and it looks fine until I start to enter something. The suggestions aren't showing well. You can sort of see them, but mostly there are cut off and the user gets scroll bars to deal with.
It seems like I ought to be able to set a style on the geocoder, but I haven't figured out which style it is. I tried .simpleGeocoder .esriGeocoderResults, which seemed likely, but that didn't fix this. I tried adding a z-index, but that didn't do anything.
