VERIFIED SOLUTION i

Adding a website as hyperlink using Template designer in Spectrum Spatial Analyst

HTML links are supported for the column elements values only, where a user can designate the column value to be displayed as a Hyperlink, Text, Email, etc. 
User-added image
Converting a text element as a hyperlink is not yet supported.
The workaround for this limitation is to edit the .html of the template manually.

Steps:
  1. Templates can be found at: \customerconfigurations\analyst\theme\infotemplates\
  2. Open the templatename.htm file where templatename is the name of the template you would like to edit 
  3. Add the below tag to add the download functionality. You need to include the name of the column if you want to update the link with any dynamic value which is coming from table.
<a target="_blank" rel="noopener noreferrer" [attr.href]="'http://YourWebsiteLink/"+ data.feature.ColumnName.value">
Text to display as hyperlink
</a>
where:
YourWebsiteLink is the link of the website and
ColumnName is the name of the column from where the value will be picked dynamically as you click on any region

For example: 
<a target="_blank" rel="noopener noreferrer" [attr.href]="'http://www.state.' + data.feature.State.value+'.us/'">

</a>

Note that in case you clone the Map config using this template or would like to edit the Template designer, all the manual edits will be lost.
Taking a backup of templates is recommended in such scenarios.
