|
<p>The <code>types</code> enables node types - each node can have a type, and you can define rules on how that type should behave - maximum children count, maximum depth, valid children types, selectable or not, etc.</p>

<h3>max_children</h3>
|
|
30
|
<p class="meta">A number. Default is <code>-1</code>.</p>
|
|
31
|
<p>Defines maximum number of root nodes (<code>-1</code> means unlimited, <code>-2</code> means disable max_children checking in the tree).</p>
|
|
32
|
|
|
33
|
<h3>max_depth</h3>
|
|
34
|
<p class="meta">A number. Default is <code>-1</code>.</p>
|
|
35
|
<p>Defines maximum depth of the tree (<code>-1</code> means unlimited, <code>-2</code> means disable max_depth checking in the tree).</p>
|
|
36
|
|
|
37
|
<h3>valid_children</h3>
|
|
38
|
<p class="meta">A string or array. Default is <code>"all"</code>.</p>
|
|
39
|
<p>Defines valid root node types (could be <code>"all"</code>, <code>"none"</code>, or an array of type strings).</p>
|
|
40
|
|
|
41
|
<h3>type_attr</h3>
|
|
42
|
<p class="meta">A string. Default is <code>"rel"</code>.</p>
|
|
43
|
<p>Defines the attribute on each <code>li</code> node, where the type attribute will be stored.</p>
|
|
44
|
|
|
45
|
<h3>types</h3>
|
|
46
|
<p class="meta">An object.</p>
|
|
47
|
<p>Defines all the active types in the tree. Each key is the type name, and each value represents the rules for this type. A <code>default</code> type is defined - all nodes with no explicit type set are treated as if they were of the <code>default</code> type.</p>

</div>
|
|
67
|
<p>For <code>max_children</code>, <code>max_depth</code> & <code>valid_children</code> use the same values as for the tree, but the value you set will only apply for that node type.</p>
|
|
68
|
<p>You can set an <code>icon</code> key - it should be an object consisting of two keys - <code>image</code> (string - location of the image to be used as an icon) & <code>position</code> (string - left and top pixels of the image - 10px 40px, only useful when using sprites - omit otherwise).</p>
|
|
69
|
<p>You can set more keys in that object - each key should be a function name, and each value - either a boolean (in order to allow or disallow that operation, on that node type) or a function. If you supply a function - your function will be called with two arguments - the name of the called function (the key) and the arguments passed to that function - you can then decide whether to return <code>true</code> or <code>false</code>.</p>
|
|
70
|
<p class="note">For any type - for now you can control only functions that take the node being manipulated as the first argument.</p>
