Hi Thomas,
You can easily create your own, empty Theme Component by going to Admin/Themes/Components.
Click on Install, and in the dialog that appears, click Create New:
On the next dialog, give it a name:
That creates an empty component. Now all you need to do is click Edit CSS/HTML:
Go to the tab called Head. There you will paste in the custome script tag that Linguise gives you when you set things up on their website:
In my image, I included some comments, but you would normally just get a blank list into which you would paste your custom Linguise URL.
Note that, working with Linguise tech support, we found that the script tag needed to be modified slightly because sometimes the page required a manual refresh when changing languages.
If you change the beginning of the tag so it starts <script defer src=… that fixes the manual refresh problem.
As a side note, these simple Custom Components can be used as a a safe and elegant way to make any overrides to the theme you are using and to affect many screen elements.
For example, on my site I have disabled a number of screen elements that I felt would just confuse my user population. To do that, on the CSS tab I added some CSS selectors with the property display: none.
For example, this suppresses the Add Section button on the sidebar:
.sidebar-wrapper .sidebar-footer-wrapper .btn-flat.add-section {
display: none;
}
The tricky part is figuring out the CSS selectors (i.e the part before the open bracket), but if you use the developer tools on your web browser, you can generally find the screen items and copy their selectors.
Good luck!
