NavMap

Components User's Guide

The following component provides a basic example of how you might do this, using a very

simple JavaScript:

<nexus:component classid="nexus/components/NavMap"

code="$nexusComponents" dwcomptype="navmap"

sitestructure="/website/ccs_sample.site">

var indent = 20;

// children indent in pixels

document.write('<img src="' + 'clear.gif' + '" height="1"

width="' + $node.level * indent + '">

<a href="$node.url">$node.name</a><br>');

</script>

</nexus:component>

In this example, the script defines a variable called

indent

, which is set to

. Then, the

script writes an image statement which defines the width of the image by multiplying the

indent value of each link by the node level (

$node.level * indent

). In this way, level 1

links are indented 20 pixels, level 2 links are indented 40 pixels, and so forth. The final

navigation menu, with indents, might look something like:

Generating Node Children Numbers

To generate the number of children that each node has in the site structure, include the

$node.children

data macro field. If the node has no children,

$node.children

returns

. Using the

$node.children

macro, you can define unique behavior or look and feel for

navigation links that do and do not have children, or for navigation links with different

numbers of children.

For example, you can define logic which states that if

$node.children

is equal to

, then

the navigation link associated with that node will have no additional links embedded

beneath it. If, however,

$node.children

is greater than

, you can define logic that will

display an arrow or other graphic that illustrates the node's relationship to other

navigation links, or build a menu that displays sub-links only when a site visitor hovers on

or clicks a node which has 1 or more children.

For example, the following site structure section has one top level node called Index, with

2 children nodes (in level 2 of the structure) called Local Offices and Find an Agent:

1 2 ... 94 95 96 97 98 99 100 101 102 103 104 ... 141 142
