I am trying to Remove a topic from CrudRepository, but the checkboxes I am trying to create don't show up.
I have an Add Method which works just fine, but the remove doesn't.
HTML: hello.html
for the navigation and head fragments

<br/>
</div>
<input type="submit" value="Remove Topic"/>
</form>
</body>
</html>
And here is what is happeneing:
Your problem is in the loop, you are using the same object to iterate itself
th:each="topic: ${topic}"
You should have something similar to this
<div th:each="item: ${topics}" class="checkbox">
<input type="radio" name="id" th:value="${item.id}" th:id="${item.id}"/>
<label th:for="${item.id}" th:text="${item.category}"></label>
<br/> <!-- Do not use this tag to add vertical space, use css classes-->
</div>
Thanks to https://stackoverflow.com/users/2757561/cralfaro we were able to fix the connection between the controller and the removeTopic.html
The problem was is the hello.html at the
<a th:href="/removeTopic">Remove</a>
and this is how it should be:
<a th:href="#{/api/removeTopic}">Remove</a>

This is my code:

<title>Taco cloud</title>
</head>
<body>
<h1>Designate your taco!</h1>
<img th:src="#{/images/TacoCloud.png}">
<form method="POST" th:object="${taco}">
<div class="grid">
<div class="ingredient-group" id="wraps">
<h3>Designate your taco!</h3>
<div th:each="ingredient:${wrap}">
<input type="checkbox" value="${ingredient.id}"/>
<span th:text="${ingredient.name}">INGREDIENT</span>
</div>
</div>
</div>
<button>Submit your taco</button>
</form>
</body>
</html>
When I press the Submit your taco button, my controller returns this html file back with
return "design";
But the problem is after the controller runs return "design",
the following part disappears:
<div th:each="ingredient:${wrap}">
<input type="checkbox" value="${ingredient.id}"/>
<span th:text="${ingredient.name}">INGREDIENT</span>
</div>
How can I fix it?

in editcourse form by giving ccode it should display all other field from database with thier value and then i can modify it
You can use either ajax or give url of jsp in form action attribute.
then in that jsp get txtRollno from request, retrieve fields from database for this rollno, populate data into appropriate field and then you can edit it and then update into database.
As other friends said you need to use ajax call and you said that you don't know ajax.
So I think these tutorials help you:
1) What is AJAX?
2) AJAX Example
3) jQuery Ajax call tutorial
Good Luck ;)

frameset is used instead of body, not inside it.
The attribute is rows, not row.
Validating would have told you this.
A frameset is used to establish a BODY, and should not be used inside of one.
Plus: You don't have a BASE target="" in your framed pages head(s).
And DIVS can be used to establish what you are trying to acheive, but referencing them can become complex quickly.
Also, naming your frames makes them much easier to deal with, and I see you've left their name references out of their declarations. There was alot of frameset debate when it was standardized, and if you are a professional author, I would suggest reading some of that information so you can see the advantages and disadvantages of framesets.
Now, with that being said, I would offer this suggestion:
IFRAME might work for you in this case, but because of the resourses and load times, esp. with building data tables, I would suggest another approach.

Well your problem is you have no doctype, html, head or body tag.
Your page will not validate, simply because you are incorrectly nesting/closing tags, and some tags do not have correct attributes to them.
First of ALL things you are talking about xhtml and added xhtml-1.0-strict tag, but your heading states: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">.
I've never in my life seen <body class="oneColFixCtr"> class, being added to <body>. You can manipulate <body> in CSS by: body {background: red;}.
There were 1x <div> tags missing! There was 1x extra </p>. Lots of tags were not ended with /. <form> was missing method and action parameter!
Also, if you want 100% perfect validation, you cant use onclick="". I added jQuery to your script.
Live example: http://kopli.pri.ee/stackoverflow/5653786.php (click here to validate)
