How to hide shapes conditionally

Two solutions are available:
NEW Use the drop formatter
Use hideBegin/hideEnd formatters

It is supported only for DOCX and ODT files.

Learn more about :drop formatter on the documentation

First solution

Since Carbone v4.3.0, the drop formatter is available to delete shapes and any element from a document. Be sure to request version 4 (or higher) of Carbone:
For the Cloud API: set the header "carbone-version":4
For the Cloud Studio: Click on the top-right "settings" icon > click on "version" > Select 4.X.X.

For the following exemple, we want to drop a round shape if a value is empty.
Include the Carbone tag {d.text:ifEM:drop(shape)} within a shape alternate text, title or description.
the d.text value is a text as a string type coming from a JSON dataset
the :ifEM is a conditional formatter checking if the value is empty.
the :hide(shape) formatter is fired if the previous condition is true. The first argument shape is required to defined the element to hide.

Locations to insert tags for:
LibreOffice: Click on the shape > Select the Draw tab > click on the draw button on the top left menu > Click on Title or Description > insert the tag
MS Word: Right click on the shape > click on "edit alt text" > insert the tag

Second solution

For the following exemple, we want to drop a line shape if a value is empty.
Wrap the shape anchor with a hideBegin and hideEnd expression.

1. Insert the drawing

A line is inserted on the ODT document.
