Does Dreamweaver CS5 let you build a navigation menu easily? Are there choices of various navigation menus--horizontal and vertical?
CS4 lets you do that with it's built in Spry menus. However the css and html coding is awfully complex for anyone wanting to alter it to their colour scheme, positioning, much the same as with anything which ships with DW in relationship to layout. Put quite bluntly it's shite.
I would be surprised if CS5 has any major improvement over CS4 in that respect. Not a lot seems to happen from version to version these days. A few add-ons that you wouldn't miss.
Since Adobes take over a couple of years back it has not improved much in my opinion. Then again where can it go because its probably reached nearing its peak. There's not a lot of scope other than to pack it out with 'take it or leave it' additions.
Nothing new to be seen here, move on.
The old navigation menu has been removed from Dreamweaver CS5. There is nothing new to replace it, apart from the Spry Menu Bar which has been part of Dreamweaver since CS3.
