Clicking elements before taking screenshots
In this example, we capture the branches of the US government website. First, this is how the webpage looks before we click anything:
The screenshot is cropped to the area where we'll click the element.
Step 1: Selecting the element
The arrow points at the part we'll click, to expand its content before the screenshot is taken. In practice, this can be any part of the webpage.

Step 2: Inspecting the element
Now that we know what to click, let's get to the mechanics. Go to that URL in your browser (we're using Google Chrome here) and right-click the part you want to click before the screenshot. In the little menu that appears, click Inspect.

Step 3: Copying the element's selector
This opens a pane, usually on the right-hand side of the screen, with the element we're targeting already highlighted. Right-click it and choose Copy > Copy selector. That's the selector we'll use in Stillio.

Step 4: Pasting the selector into Stillio
Now head over to your Stillio account and add this URL: https://www.usa.gov/branches-of-government. Open the Advanced settings tab, type the selector you copied into the Click field and press Enter. It should look something like this (see all advanced capture settings):

When you add the webpage with these settings, our render engine clicks the selected element and renders the page like this:

Congratulations! 🎉 Stillio now clicks that element before taking the screenshot. You can use the same trick for any element on the page, like newsletter or subscription pop-ups, or anything else that gets in the way of your screenshots.
