In the previous post, I have tried to play around with the width of the drop down popup of the Flex DropDownList. An interesting observation is that the drop down is always aligned to the left edge of the open button of the DropDownList. Now it could be a requirement to open it aligned to the right edge or even centered with respect to the open button. So how to achieve that?

But we have also seen that it is a bit flaky, in the sense, the width of the popup jumps around when it encounters content that is longer than any it has been displaying previously. This is because the drop down uses the DataGroup which creates itemRenderers judicially on a “as needed” basis. In some cases, it might be better if the popup opens up to a fixed width to give a consistent UI performance. Again, the standard DropDownList does not allow for it and we have to make a simple tweak to make this happen.

The problem is that when using the Spark controls like the DropDownList, the actual drop down that displays the list of options is defaulted to the width of the DropDownList component. If the length of options are greater than the width of the component, then a horizontal scroll bar appears automatically. Now, horizontal scroll bars are a bit of pain and never look good on a GUI. However, there is a very easy way in which the DropDownList can be made to auto expand to the length of the options it displays. Read More
