The mortgage broker website we supply clients includes a comprehensive calculator archive with around 40 calculators shipped by default - this includes a number of our own tools, and some supplied under licence to you by the MFAA or FBAA.
A few days ago we introduced revised basic LVR and DTI calculators, with both rendering as slider-based tools. They're designed to be shown inline in content, as we need to provide context for content when a user is reading without sending them to another page (or showing a simple definition tooltip).
We've just updated Elementor to include a drag-and-drop widget. Every single line of text, colour, slider value, and the default start values, can all be defined from within the Elementor block. That said, the single shortcode is simple to use. The update will push on Wednesday.
As with all tools, ensure that you provide appropriate disclaimers.
The image includes screenshots of the Elementor block, and the second image shows example results.
