update:I find the style setting in EPiServer.Cms.Shell.UI.zip,but should we change that,I think it's not good.
As far as I know this is fixed inside CMS package. You can try to override this style in your own CSS. Maybe will affect edit mode language selection.
Thank you,Valdis.currently I have overriden the style to 200em.Hope next epi update to remove that.
Because this is the first time to new thread for epi,I 'm not sure this is corrrect category here.I encountered the following problem after upgrade to 8 from 7.5 as the instruction http://world.episerver.com/documentation/Items/Installation-Instructions/Installing-EPiServer-updates/ ,including refered to http://world.episerver.com/link/3381e12654c04ace971fe8a3d90ae081.aspx?id=115661 ,
It seems to big change style for multi- Languages in edit model, I think epi support can give good solution for help.
the element class is ".Sleek .epi-previewableTextBox-text",which is including "max-width:15em" caused this issue.so how can I remove this or should any other ideas?
