+## setWrap
+
+### Description
+
+Determines whether the child objects should wrap onto the next line when there isn't enough room along the main axis. The default value is 'nowrap'.
+
+### Parameters
+
+1. `string` If set to `wrap`, the child objects will wrap onto the next line when they run out of space. If set to `nowrap`, they will not.
+
+### Returns
+
+1. `object` The object in use
+
+### Usage
+
+* Creates a default Flexbox and sets the wrapping to `wrap`.
+
+```lua
+local main = basalt.createFrame()
+local flexbox = mainFrame:addFlexbox()
+      :setWrap("wrap")
+```
+
+If the contents of the Flexbox exceed its size, they will automatically move to the next line, creating a wrapping effect. This is particularly useful when designing responsive layouts that adapt to different screen sizes or window dimensions.
