Group Navigation Bar Tool - Configuring the Drop-Down Levels

The first step in configuring the drop-down levels is to use the Auto Configure Max Levels per View check box on the General page to indicate whether the levels will be auto-configured or you will manually configure them.

To manually configure the levels, clear the Auto Configure Max Levels per View check box.

To auto-configure the levels, select the Auto Configure Max Levels per View check box. When levels are auto-configured:

The number of drop-down levels depends on the number of levels in the navigation hierarchy. There are one or more drop-downs than there are levels in the hierarchy.
The first drop-down contains the name of the navigation view.
The last drop-down contains the list of facilities, provided that the Show Target check box on the General page is selected.
The drop-down widths are set by the drop-down level’s label or by the contents of the drop-down, whichever is larger.
The sort criterion is Facility Description.
Filtering is disabled.

This topic describes how to manually configure drop-down levels for the Group Navigation Bar tool. It includes the following sections:

Levels Properties

Use the Levels page in the CygNet Group Navigation Bar Control Properties dialog box to manually configure drop-down levels.

Group Navigation Bar Control Properties - Levels Page

The following table describes the Levels page properties:

Property	Description
Level	Identifies the drop-down level being configured.
Max Levels	Specifies the total number of drop-down levels in the tool. The default is 3.
Display Text	Defines the text to display for the drop-down level. Select an option from the drop-down list of group service attributes. For more information, see Filtering and Sorting a Drop-Down, below.
Filter	Defines the filter criteria for the drop-down level. For more information, see Filtering and Sorting a Drop-Down, below.
Sort	Defines the sorting criteria for the drop-down level. For more information, see Filtering and Sorting a Drop-Down, below
Chooser Label	Defines a label for the drop-down level. If you select Attribute, a group service attribute is used as a label. Attribute is the default. If you select Text, the Text that you enter in the field is used as the label.
Width	Specifies the width (in pixels) of the drop-down level. Select Variable if you want the width to be automatically configured and the levels to be scaled in relation to each other. Variable is the default. Select Fixed if you want to specify a width for the drop-down, and enter that width (in pixels) in the field. To hide a level, select Fixed and enter a width of 0.

Filtering and Sorting a Drop-Down Level

To manually configure a drop-down level, select the display text, apply one or more filters, and define the sort criteria.

Note: Display Text, Filter, and Sort criteria are Group Service attributes, not Facility Service Attributes.

Although some Group Service node attributes are based on Facility Service attributes, be sure to define the display text, filter, or sort criteria with Group Service node attributes in mind.

The following table lists Group Service node attributes, based on Facility Service attributes:

Group Service Node Attribute	Facility Service Attribute
Description (~desc)	Description
Attribute0 (~attr0) - Attribute 21 (~attr21)	Text attributes 0 - 21 with alphanumeric string values
Yes/No Attribute 0 (~attryn0) - Yes/No Attribute 19 (~attryn19)	Attributes 0 - 19 with only "Yes" or "No" values
Application 0 (~appl0) - Application 5 (~appl5)	Text application attributes 0 - 5

Configuring a Drop-Down Level

A drop-down level only includes facilities that meet the filter criteria.

When you define a filter, be sure to define it at the correct level.

For example, imagine that your navigation view included the attributes State, Route, and Type. If you wanted to filter the drop-down level to include only facilities that had an attribute value of “SWD,” the levels would be:

Level 0 — Name of navigation view (State, Route, Type)
Level 1 — State
Level 2 — Route
Level 3 — Type
Level 4 — List of facilities (leaf nodes)

You would define the filter on Level 3.

To configure a filter

In the CygNet Group Navigation Bar Control Properties dialog box, click the Levels tab.
On the Levels page, use the Level menu to select the level for the filter you are defining.
Click … next to the Filter field to display the Select Level Filter Criteria dialog box.

Select Level Filter Criteria

Click the Add button to display the Rule Definition dialog box and begin specifying rules for the filter. For information about CygNet filter rules, see Using CygNet Filter Rules.

Rule Definition

Note: To list Group Navigation Bar Custom Attributes, select Reference Attribute as the Comparison Type, then view the Comparison Item field.

When you finish defining the filter, click OK.

Configuring a Drop-Down Sort

By default, drop-down levels are sorted in alphabetical order by the Description attribute of the Group Node. You can change this default sort order as follows.

Note: When you define a sort order, be sure to define it at the correct level.

To configure a sort

Show the properties for the Group Navigation Bar object.
Click the (OCXProperties) property on the ActiveX page in the object’s Property Sheet.
On the Levels page in the CygNet Group Navigation Bar Control Properties dialog box, select the Level for the sort.
Click … next to the Sort field to display the Select Sort Criteria dialog box.
Select a criterion in the Sort Criteria field and click Insert >.
Add more criteria as desired.
Use the Move Up and Move Down buttons to change the order of the criteria.
Click OK.
