Linking a "expand all" button to article titles that drop down

Hi,

I need to connect the "button" and "article_link" selectors, so that the "button" clicks "expand all" to display all the article titles, and then selects each article link individually to extrapolate each article's data individually.

Which selector should be a parent of child of each other? How do I connect the two selectors so that I can extrapolate the data for each article (content inside each article / poster link)?

I suppose you don't need any clicks on plus to expand data.... All you need is already loaded
