Freemarker iterating over hashmap keys

Question

Freemarker has two collection datatypes, lists and hashmaps Is there a way to iterate over hashmap keys just as we do with lists?

So if I have a var with data lets s

Answer 1

For completeness, it's worth mentioning there's a decent handling of empty collections in Freemarker since recently.

So the most convenient way to iterate a map is:

<#list tags>

    <#items as tagName, tagCount>
        
{$tagName} (${tagCount})
    

<#else>
    
No tags found.

No more <#if ...> wrappers.
