Pull Nested Child Categories by Parent Category Key


Use this example to create dynamic parent/child category listings.  The category listings can then become clickable listings to filter content by category.. used in menus, etc...


${esc.hash}${esc.hash}set the myCategoryKey variable to your parent category key name (see properties on your category and make sure it is set)
${esc.hash}${esc.hash}this example will show you how to pull the children and nested children of a category

${esc.hash}set(${esc.dollar}myCategorykey = "yourCatKey")

${esc.hash}foreach(${esc.dollar}con in ${esc.dollar}categories.getChildrenCategoriesByKey("${esc.dollar}!{myCategorykey}"))
<h2>${esc.dollar}velocityCount. Parent Category Properties</h2>
<p><strong>Velocity Variable Parent Category Name:</strong> ${esc.dollar}!{con.categoryVelocityVarName}<br/>
	<strong>Parent Category Name:</strong> ${esc.dollar}!{con.categoryName}<br/>
	<strong>Parent Category Key:</strong> ${esc.dollar}!{con.key}

	<h4>Pull of Next Level Child Category Names</h4>
	${esc.hash}foreach(${esc.dollar}child in ${esc.dollar}categories.getChildrenCategoriesByKey("${esc.dollar}!{con.key}"))
${esc.hash}${esc.hash}Here in the list you could href a url map pattern that includes the category and go to a detail page that lists content by category based on the path: /someMapPattern/somecategory/ (see url map doc here http://www.dotcms.com/docs/latest/URLMapSEOFriendlyURLs)

${esc.hash}${esc.hash}Keep nesting foreach loops in the "Pull of Next Child Category Names" to dig deeper into your category lists
