Navigating with the Horizontal Menu Component
The Horizontal Menu component enables you to build a menu structure by setting up multiple links to different page URLs from the component. Our example has a menu with links to three internal pages and one external page on the Internet.
This example shows a Horizontal Menu with four items. Three items are linked to views within the Perspective project and the fourth is linked to a website. The third item in the list, Field Offices, has four subitems.

Initial Project Setup​
To begin with we have created three views: WestView, EastView, and Welcome. They are each coordinate type views. As we create each new view, we checked the Page URL property and added a page name.
| View Name | Page URL | 
|---|---|
| WestView | /west_page | 
| EastView | /east_page | 
| Welcome | / | 

On Page Configuration, you'll note that each page is already set up with a Primary view.

Now we're ready to start building the navigation.
Set Up a Header View​
The first thing we'll set up is a view that will hold the Horizontal Menu component. We'll use this view as a header for our pages within this project.
- In the Project Browser, right click on Views and select the NewFolder - option. Name the folder "Header". 
- Right click on the Header folder and select the NewView - option. - Name: Horizontal-Menu-Nav 
- Layout: Coordinate 
- Page URL: unchecked  
 
- Click Create View. 
- In the Property Editor for the view, set the defaultSize property as follows: - width: 800
- height: 50
 
- Drag a Horizontal Menu component onto the view. 
- In the Property Editor, set the Position Properties as follows: - Property - Value - position.x - 15 - position.y - 10 - position.width - 550 - position.height - 30 
- In the Property Editor, scroll down to style and click the ModifyStyle - icon. - Expand the Text section and set the style options as follows: - Property - Value - props.style.fontWeight - bolder - props.style.fontFamily - Verdana - props.style.fontSize - 14px 
- Expand the Border section and set the style options as follows: - Property - Value - props.style.borderStyle - solid - props.style.borderColor - #555555 - props.style.borderRadius - 16px - All Corners - (selected) 
 - Your Designer will look like this at this point:  
- Open Page Configuration by clicking on the Settings - icon at the bottom left of the Designer window. 
- Under Page Configuration, click on Shared Settings. 
- In the header part of the page mockup, click on the Add - icon. 
- Select the Horizontal-Menu-Nav view from the dropdown.  
- Click OK. The Horizontal-Menu-Nav view will now appear at the top of all pages in the project. 
Configure the Tabs in the Horizontal Menu​
Now let's set the properties for each of the four tabs in the Horizontal Menu. Each tab will have a display a name and an icon and will have a target page or website to open when clicked.
- In the Property Editor, expand the items property and set the following for item 0: - Property - Value - props.items.0.enabled - true - props.items.0.target - /west_page - props.items.0.icon.path - material/explore - props.items.0.icon.color - #D97700 - props.items.0.label - West Site - The Property Editor will look like this:  
- In the Property Editor, set the following for item 1: - Property - Value - props.items.1.enabled - true - props.items.1.target - /east_page - props.items.1.icon - material/store - props.items.1.color - #D97700 - props.items.1.label - East Site 
- In the Property Editor, set the following for item 2: note- Do not set a props.items.2.target property value for this tab because we will set up dropdown tabs in the next section. - Property - Value - props.items.2.enabled - true - props.items.2.icon.path - material/landscape - props.items.2.icon.color - #D97700 - props.items.2.label - Field Offices 
- In the Property Editor, set the following for item 3: note- This tab uses a website as its target, therefore it does not need to target a page within Perspective. - Property - Value - props.items.3.enabled - true - props.items.3.target - http://inductiveautomation.com/about/ - props.items.3.icon.path - material/people - props.items.3.icon.color - #D97700 - props.items.3.label - About 
Configure the Field Offices Tab in the Horizontal Menu​
The third tab in the Horizontal Menu is titled "Field Offices." Instead of navigating to one page, this tab has a dropdown menu with four options on it: Reservoir, Dock, Warehouse, and Surveillance.
- To start, we created a new folder in Views called Field.  
- Within the Field folder, we create four views: Reservoir, Dock, Warehouse, and Surveillance. Make them Coordinate types and set up a page URL for each. - View Name - Page URL - Reservoir - /reservoir_page - Dock - /dock_page - Warehouse - /warehouse_page - Surveillance - /surveillance_page 
- Open the Horizontal-Menu-Nav view and select the Horizontal Menu component. 
- In the Property Editor, expand the properties for Item 2.  
- Select the props.items.2.items property. 
- Click the Add - icon to add four items. 
- Set the properties for Item 0 as follows: - Property - Value - props.items.2.items.0.enabled - true - props.items.2.items.0.target - /reservoir_page - props.items.2.items.0.icon.path - material/rowing - props.items.2.items.0.icon.color - #00ACAC - props.items.2.items.0.label - Reservoir - The Property Editor will look like this:  
- Now we'll do the same for the other three items. Set the properties for Item 1 as follows: - Property - Value - props.items.2.items.1.enabled - true - props.items.2.items.1.target - /dock_page - props.items.2.items.1.icon.path - material/directions_boat - props.items.2.items.1.icon.color - #9E6635 - props.items.2.items.1.label - Dock 
- Set the properties for Item 2 as follows: - Property - Value - props.items.2.items.2.enabled - true - props.items.2.items.2.target - /warehouse_page - props.items.2.items.2.icon.path - material/local_shipping - props.items.2.items.2.icon.color - #0000AC - props.items.2.items.2.label - Warehouse 
- Set the properties for item 3 as follows: - Property - Value - props.items.2.items.3.enabled - true - props.items.2.items.3.target - /surveillance_page - props.items.2.items.3.icon.path - material/videocam - props.items.2.items.3.icon.color - #AAAAAA - props.items.2.items.3.label - Surveillance 
- Save your project. 
- Click Tools > Launch Perspective > Launch Session. 
- Click on the tabs in the header to view different pages. For our example, we have put a few components on each view. Here is an example of what the Field Offices > Reservoir page might look like:
