There are different ways to insert HTML code dynamically and run it, depending on the programming language and framework used. Here is a general approach:

1. Get the HTML code as a string variable, either from user input or from a server response.
2. Determine where to insert the HTML code dynamically. This could be a certain DOM element in a web page, a modal dialog, or a popup window.
3. Use a DOM manipulation method to insert the HTML code into the appropriate place. For example, in JavaScript, you could use the innerHTML property of an element to set its content to the HTML code.
4. If the HTML code contains scripts that need to be executed, create a new script element and set its content to the script code. Then, append the script element to the DOM element where the HTML code was inserted.
5. Optionally, you may need to wait for the script(s) to finish loading or executing before proceeding with other actions. This can be achieved using callbacks, promises, or async/await syntax.

Here is a sample code in JavaScript that inserts HTML code dynamically and runs its scripts:

let htmlCode = "<div><h1>Hello, world!</h1><script>alert('Welcome!');</script></div>";
let element = document.getElementById("my-element");
element.innerHTML = htmlCode;
let newScript = document.createElement("script");
newScript.innerHTML = "console.log('Script executed.')";
element.appendChild(newScript);

This code inserts a <div> element containing an <h1> tag and a script that shows an alert message. Then, it creates a script element that logs a message to the console and adds it to the same <div> element. When the code runs, the HTML code and scripts are inserted and executed dynamically.
