Category legend type

There are 2 types of category legends you can set for your needs.

• Multiple Selection: Multiple selection means that more than one categories can be shown at the same time if they are toggled on in the legend. Each category item comes with a checkbox, so checking this box will display all the overlays that are assigned to this category on the map.
• Single Selection: Single selection means that only overlays of one category can be shown at one time. Each category item becomes a hyperlink, and selecting one category will hide the overlays of other categories on the map.

Category legend and item settings

You can compile your list of your categories in your desired order in this section.

1. Use the Add Legend Item button to add a new item into the legend. If you have already created some categories before, you will be prompted to add them into the legend automatically. Click Yes to add them automatically, or No to add a normal item for further changes in the next steps.
2. You can choose the type of the item it represents and associate it with any categories you have created under Category Legend Item Settings section.
   • Item Type: Define the type of the selected item in the legend. Choose Category Item if the legend item is associated with a category. Choose Title if the legend item is a text description only. Title items are displayed in bold text in the legend.
   • Description: The name that is displayed in the legend. If it is a category item created by adding the categories automatically, the description will share the same name of the category. You can change it to your desired designation.
   • Category ID (Category Item Only): Associate the legend item with the category here, and this setting is disabled for Title items. Choose the name of the category from the drop down menu. You can also choose No Category from the list to represent any objects not added to your defined categories.
