You can link many different types of content to a showcase hotspot.
To link content or collateral to a hotspot:
Once content is added to a hotspot, the ‘Add content’ option will change to indicate the type of content that has been added - for example, ‘Linked Video’ or ‘Linked Images’. You can change this at any time by clicking this option and assigning different content as above.
You will need to publish any changes in order for them to take effect.
Linking URLs that aren't websites
To link to an email address in a way that prompts a mail client (like Outlook or the iPad 'Mail' app) to open, you put "mailto:" before the address in the URL field. This is with no spaces & capitals. So if the email address is email@example.com, then you'd put mailto:firstname.lastname@example.org like in the image.
You can also use sms: and tel: in the same fashion with phone numbers, but be aware this will only work on phones!
Links to other apps
You can also get a URL to trigger the opening of another app installed on the device. We have another article about this practice specifically.
If you're feeling advanced, you can also add HTML5 content to a hotspot. More details are here.
