        The following attribute datatypes exist:
        </p>

        <p>
        <strong>text</strong><br>
        This datatype is used for simple text attributes. A maximum length may be specified.
        </p>
        <p>
        <strong>password</strong><br>
        This datatype is used for password attributes. Several encryption methods are available. Passwords will not be displayed in the GUI.
        </p>
        <p>
        <strong>select</strong><br>
        This datatype creates a drop-down menu. A list of possible values must be specified.
        </p>
        <p>
        <strong>assign_one</strong><br>
        This datatype creates a drop-down menu that allows an item of any class to be assigned to another one (the selected item will be linked as &quot;parent item&quot; by default).
        </p>
        <p>
        <strong>assign_many</strong><br>
        This datatype creates a menu that allows an item of any class to be assigned to one or more other items (the selected items will be linked as &quot;parent items&quot; by default).
        </p>
        <p>
        <strong>assign_cust_order</strong><br>
        This datatype is identical to &quot;assign_many&quot; but can additionally handle the order of how items are assigned.
        </div>
    </div>

    <div id="predef_value" title="predefined value">
        <p>This option allows you to predefine a default value for any attribute. Different options are available depending on the datatype of the attribute:</p>
        <p>For <strong>text</strong> attributes: a predefined text value.</p>
        <p>For <strong>select</strong> attributes: one of the options from the "list of possible values"</p>
        <p>For <strong>assign_one</strong> attributes: an item to be pre-assigned.</p>
        <p>For <strong>assign_many</strong> and <strong>assign_cust_order</strong> attributes: one or more items to be pre-assigned (multiple items separated by "<strong>::</strong>")</p>
    </div>

    <div id="max_length" title="max length">
        <p>The character limit for an attribute within the NConf GUI.</p>
        <p>Possible range: 1 - 1024</p>
        <p>This option is only available for attributes of datatype "text" and "password".</p>
    </div>

    <div id="link_as_child" title="link as child">
        <p>
        This flag determines if items from another class should be linked as an item's children rather than being linked as parent items.</p>
        <p>
        Example: when a user adds hosts to a hostgroup, he intends the hosts to become child items of that hostgroup. By default, items that are selected in a menu will always be linked as parent items. In this specific case, the "link as child" flag needs to be set to prevent the hosts from becoming the parents of the hostgroup (here we want it the other way around).
        </p>
    </div>

    <div id="link_bidirectional" title="link bi-directional">
        <p>
        This flag affects the visibility of "assign_" attributes in the NConf GUI. It is used where users wish to manage the link between two items in more than just one GUI. This flag will make the same attribute available on both sides of the assignment.
        </p>
        <p>
        Example: a user wishes to set the link between contacts and contactgroups using both the contacts GUI and the contactgroups GUI. Setting the "link bi-directional" flag will display the same menu on both sides, even though the attribute actually only exists in one class.
        </p>
    </div>


    <div id="mandatory" title="mandatory attribute">
        <p>
        Defines if this attribute should be mandatory. Users will be forced to set this attribute.
        </p>
    </div>

    <div id="visible" title="attribute visibility">
        <p>
        Defines if this attribute should be visible in the NConf GUI.
        </p>
        <p>Note: this flag will only affect the GUI. Invisible attributes will still be stored in the background. Also, invisible attributes will be written to the Nagios configuration, as long as the "write to configuration" flag is set to "yes".
        </p>
        <p>
        Invisible attributes can be very useful in conjunction with an attribute's "pre-defined value".
        </p>
    </div>

    <div id="conf" title="write to configuration">
        <p>
        Defines if this attribute should be written to the Nagios configuration files. 
        </p>
        <p>
        This flag is most useful to distinguish NConf specific attributes from actual Nagios attributes.
        </p>
    </div>

    <div id="ordering" title="ordering">
        <p>
        Defines the order in which this attribute will be displayed in the NConf GUI. If this field is left blank, NConf will automatically assign the next available order number.
        </p>
    </div>

    <div id="naming_attr" title="naming attribute">
        <p>
        Defines if this attribute is the "naming attribute" of the current class. The "naming attribute" (i.e. the primary key) is used to distinctively identify an object within its class. 
        </p>
        <p>
        There can only be one "naming attribute" in each class. Likewise, there can only be one item with the same name within a class.
        </p>
    </div>
