+## show
+
+### Description
+
+The `show` method makes the object visible if its parent frame is visible. If the parent frame is hidden, the object will not be displayed until the parent frame is shown.
+
+### Returns
+
+1. `object` The object in use
+
+### Usage
+
+* Show a button:
+
+```lua
+local basalt = require("basalt")
+
+local mainFrame = basalt.createFrame()
+local button = mainFrame:addButton()
+button:show()
+```
+
+In this example, a button is added to the mainFrame and the show method is called to make it visible.
+
+```xml
+<button visible="true" />
+```
+
+The show method allows you to control the visibility of the object within its parent frame.
