Selection width problem in custom multifield

[narayanank84409]

Created new Custom Multifield, it's accepting all the fields (Ex: Textfield,pathfield,selection.). Gave width to all.

Values are storing in crx..

When i open the dialog, width for Selection is not working. it's automatically going back to 0px.

Am not sure how to fix this.

Tried (width property).

Please suggest
