You can use inline xslt:

but I dont know about using an if statement.

You would probably just want to either create a macro (that uses XSLT) or use javascript.

Hiya Vincent you could do the following:

As templates are .NET masterpages you could drop in an asp:checkboxlist control directly onto the masterpage and create a codebehind file in Visual studio to do your code

OR the best practise & common way is to have any dynamic functionality (such as forms etc) put into a ASP.NET usercontrol.

To add a .NET usercontrol to your template you need to:

• Add the usercontrol .ascx file in the /usercontrols folder
• Copy the compiled code (.dll) to the /bin directory
• Login to Umbraco and goto the Developer section
• Right click on the macro folder and click create/new
• Give your macro a meaningful name - eg contactform
• On the macro use the dropdown next to .net usercontrol and browse to your .ascx file
• Ammend the alias to suit your coding style (camelCase) or whatever
• Hit Save
• Goto your template/masterpage you wish to add the macro to in Umbraco
• Then click the fourth icon from the left (has this as the icon ><)
• Choose which macro you wish to insert into the template
• Save the template & volia you have your .NET usercontrol running in your template

I hope this helps you out.
