Legend Content Alignment

Using Flex 2.2 Dynamic Legend

The legend in 2.2 is working beautifully, but I have one question. The legend is displaying the label followed by the icon, which is on the next line. In the sample pictures, the label and icon appear to be on the same line.

Any idea why mine is displaying on seperate lines? I assume it may have to do with the length of the labels, but I wasn't sure where to adjust for that.

Thank you.

I'm not able to reproduce this. When I make the Legend component too small, I get horizontal scroll bars. Can you try updating this with your service?

Dasa,

I think I have figured out what is occurring. I have various crime types seperated into different layers, as I want the user to be able to turn on/off individual crime types. I didn't see an easy way to do this with sub-layers.

With that said, what I am seeing is actually the layer title with the icon on the next line. If I add multiple category icons (such as Drug Violations in the attachment), it displays the icon next to the category as I desire.

Is there a better way to accomplish this?

Thank you.

For the record, in ArcMap\LayerProperties\Symbology Tab, I added a legend label as a test. This labeled the symbol, but then I end up with the same thing repeated on two lines.

You can turn on and off the sub-layers of a dynamic service by setting the visibleLayers property:
