This is something that we really need to explain better, and I’m very sorry for any confusion we have caused you.
If you want to use the control in a new project, you can actually just open the project you downloaded from https://wireframestogo.com, and start working in that. All Wireframes to Go .bmpr files are empty except for that one control.
If you want to add it to an existing project, just follow these steps:
- Open both the project you’re working on and the Wireframes to Go Project and put side by side.
- In each, go to View > Symbols
- In the Wireframes to Go project, you should see a symbol named after the control you wanted to add to your project. You can simply drag that symbol into your current project, and that will add it.
Here is a gif demonstrating that:
Once you have dragged the symbol into your project, it will be searchable, and show up in the UI library under Symbols.
I’m sorry again for not having better documentation for this. I will remedy that ASAP.
