How to create a confirmation button or link
After setting the “Allow access” settings to confirmation button, some info will display below the stack in the editor. There you will see some values you need to use as well as some instructions on how to create a link or button.
- In this example we will be using Stacks’ built-in button. You can add the button anywhere on the stacks page.
- In the button’s settings panel select the “Set link” button. In the window that opens add any value after the “#” (Example: #unlock). Note: If this anchor tag is left blank, the browser will jump back to the top of the webpage when the link is clicked.
- Click the “+” button to add a new attribute. In the “Name” column add class and in the “Value” column add the value that is provided in the instructions below the stack in the stacks editor. Do not forget to add the underscores “_” and do not add any spaces.
- Click “Set link” to finish. When this button is clicked, the content of the associated stack will automatically be converted into HTML. Visitors will have full access to the content.
How to support iframe videos/content
Iframe content cannot be converted into a canvas image so iframes will show up blank until the content is unlocked. There is a work around however, you can create a thumbnail image or screenshot of the video player to serve as a placeholder until the content is unlocked.
After you have created a thumbnail, set the “Content type” to add a watermark. Place the image in the “Image watermark” setting and then set the opacity to 100%.
