MapSVG 3.2.x tutorial

2. Templates

When you need to show information about a Region or Database Object on a map - you have to set up a Template.

Templates are pieces of Text/HTML code with extra tags which look like this: {{my_custom_field}}.

Those tags are Handlebars markup. You can find more information about Handlebars here:

Let's start: click on Choose SVG file... and type in "usa.svg". You'll see suggestions with file names containing "usa.svg" string. Choose /geo-calibrated/usa.svg file.

When possible, always choose geo-calibrated maps over non-calibrated. Geo-calibrated maps are newer, have Region titles and you can add Markers by geo-coordinates (latitude/longitude) or just by entering an address which is being converted into coordinates automaticlly.

Switch to Menu > Regions. This settings section contains a list all active (clickable) objects from SVG file. These objects are called "Regions" in MapSVG - which are US states in our case with USA map.

If you use any of the included geo-calibrated maps, each Region already has 3 fields: id, title and status.

Key difference between Region id and title is that id can't have spaces. Also id can't start with a number. Title doesn't have those limitations. That's important to keep in mind if you are creating a custom SVG file.

Let's create our first temlate. We will show state name in a tooltip on mouse hover over a state. Switch to Menu > Templates and choose Region tooltip template.

Enter the code below into the template field:

State: <b>{{title}}</b>

The template code is regular HTML code with extra Handlebars tags. You can find more info about Handlebars here -

When you hover the mouse pointer over a state, MapSVG passes that state into Region tooltip template - and you can use any default or custom fields of a Region in the template - with the help of Handlebars tags.

So if you want to show a title, just add a tag which looks like this:


If you want to show a custom field with the name my_field, do it the same way:


Now that we have our template ready, we need to switch to Menu > Settings and turn on tooltips: Tooltips: ON.

Make sure that map is switched to Preview mode (buttons on top of the map) and then try to hover the mouse pointer on any of the states. You should see a tooltip.

Handlebars markup also allows us to use logical conditions in templates:

{{#if something}}...{{/if}}


{{#unless something}}...{{/unless}}

Also we can go through a set of objects (for example if Region or Database Object have multiple attached images):

{{#each images}}...{{/each}}

Let's see how it works.

Switch to Menu > Regions. Click on Edit fields button in the toolbar.

Add Checkbox type field and name it "Visited". Add Image type field and name it "Images".

Click Save fields button and then click on List button in the toolbar to return to the list of states.

Switch the map to Edit regions mode (buttons above the map) and then click on any state, for example California. Editing form appears on the right. Check "Visited" checkbox. Repeat for a few more states.

Switch to Menu > Templates > Region tooltip again. Change the template code to this:

State: <b>{{title}}</b><br />

{{#if visited}}

{{#unless visited}}
  Want to visit!

Switch the map to Preview mode and hover the mouse pointer over states which you checked as visited and then on others - to see the difference in tooltips.

Now go to Menu > Regions. Click on California state and then in appeared form on the right - click Browse... button in Images field. Attach multiple images to the state (hold down Shift key while you choose images).

Go back to Menu > Templates > Region tooltip. Change the template code to this:

State: <b>{{title}}</b><br />

{{#if visited}}

{{#unless visited}}
  Want to visit!
<br /><br />

First 2 images:<br />
<img src="{{images.0.thumbnail}}" width="40px" />
<img src="{{images.1.thumbnail}}" width="40px" /><br /><br />

All images:<br />
{{#each images}}
    <img src="{{thumbnail}}" width="40px" />

Make sure the map is in Preview mode and hover the mouse pointer over the state which has multiple attached images - to see the tooltip.

Now we're ready for the next tutorial: 3. Regions as links
