Yes, it’ll still be responsive. The max. width setting just limits the maximum width of the ticker, it’ll resize responsively to any browser dimension less than the max. width.
All Ditty are set to fill the width of their container element 100%. So, if you have one added to a div/section on your site that is 400px, the Ditty will be 400px and also resize responsively to the parent elements width. If the Ditty is within an element that is 100% of the browser width, the Ditty will be 100% of the browser width. The only situation where issues can occur is if the container element has a display of “flex” and is expecting to get it’s dimensions from the elements within it. This sometimes happens with various builders because they are building columns using flex display, but don’t set any width dimensions. If there is no width to the container element and there are no other elements within the container that renders some sort of width, the Ditty has no width which to based it’s dimensions off of. In this case you need to most likely addd a bit of custom css to make the containing element have a width. The way to do this can vary based on how the site is setup.
Can you explain more on what you mean by “wide width” or “full width”? Are you wanting the ticker to expand the full with of the site even if it’s contained within a section that isn’t the full width of the site? This currently isn’t possible and was not a feature of the legacy ticker.
I see your ticker scrolling full width at the bottom of your site. Are you wanting this displayed somewhere else instead and having issues with it displaying the way you want? If so, let me know what you’re trying to accomplish and I can help you find the solution.
