Add advanced algorithmic filtering to any element on your page.

• + Allows you to conditionally display any element on your page, based on a javascript formula.
• > If it evaluates to true, the element appears.
• Executes once, on page load.
• + Elements are visually hidden until the logic is run to determine filtering.
• - Not useful for secure content. A determined user can view source and see your hidden element content, or play with CSS to make it visible ( on their computer only ).
• Filtering expression is inline, and can be any legitimate Javascript expression.
• Example uses
• > Filtering elements by different times of the day, different days of the week, weeks of the year, seasons, and so on.

Add advanced algorithmic filtering to your collection lists or to any element on your page.

• + Allows you to call a custom function that you define, which will decide whether or not to show each individual element.
• > + The function can do anything you want, including calling external services, to make its determination.
• > + This is particularly useful for e.g. specific date calculations which Webflow's filtering cannot support.
• This is most useful when your logic is too long or complex to specify in the attribute value with wfu-filter
