+## Description
+I want to use a FloatingActionButton to navigate to a specific step in a RadWizard based on the step's title. The wizard has a dynamic number of steps, so I cannot rely on the index number. Additionally, I need to hide or disable the "Next" button in the wizard and then show or enable it from the code-behind.
+
+This KB article also answers the following questions:
+
+- How can I navigate between wizard steps using custom controls?
+- How do I control the visibility of the RadWizard Next button?
+- Is it possible to activate a specific RadWizard step using JavaScript?
+
+## Solution
+
+### Jump to a Specific Wizard Step Using FloatingActionButton
+
+To navigate to a specific RadWizard step using a FloatingActionButton based on the step's title, follow these steps:
+
+1. Add the RadWizard and RadFloatingActionButton to your page.
+2. Implement a JavaScript function that iterates through the wizard steps, finds the desired step by title, and sets it as active.
