Hi Thiago

Thanks for posting in the Lucidchart Community! Lucidchart allows you to create custom shapes and to format shapes using conditional formatting. While there is not a feature built into Lucidchart in which you can create custom Smart Containers or similar shapes you may be able to create custom shapes or use conditional formatting to create a similar style of shape. For information about customized shapes and conditional formatting please visit the Add and customize shapes article and Add conditional formatting article in the Lucidchart Help Center.

If you are unable to create the desired component we'd love for you to add this idea to our Feature Request form. These requests are passed on to our development team for consideration and are taken very seriously as we work to improve Lucidchart. 

Please let me know if you have any further questions!
