Currently Elementor still lacks a function that you can give several boxes next to each other the same height or that is oriented to the highest box.
Solution: With some CSS you can fix this problem. First you have to create another section within a section. This section can have e.g. three or four columns. In each column you position the desired content. The CSS class must then be assigned to the inner section.
.equal-height-content { height: 100%; display: flex; }
