I've created a SkinObject for DotNetNuke that replaces the default SolPart menu control with DevMansion.com's SmartLinks menu control. This menu control adds unmatched compatibility with web-browsers across different OS's. I'm currently fixing the last couple bugs, and testing it quite heavily before I release it for free, the only catch is you purchase a valid license from devmansion.com starting at $49! However I recommend that you purchase the $149 SD Smartlinks Pro License that includes the TreeLink control.
These packages include MenuLink and TreeLink controls. ROYALTY-FREE, LIFE-TIME license (all upgrades are for free).
Single Developer License US $149
Enterprise License US $299
Enterprise + Source Code License US $499
Any donation would be greatly appreciated and will go directly to the development of free extensions for the DotNetNuke community.
