<script   src="https://code.jquery.com/jquery-3.5.1.js"></script>
<script>

can you put your code here? because then we can get better understanding. – Eranga Gamagedara Jul 24 '20 at 08:24
yes you need to import jquery ui after the jQuery. – Eranga Gamagedara Jul 24 '20 at 08:36
For more details refer this link. https://jqueryui.com/dialog/ and https://api.jqueryui.com/dialog/ – Eranga Gamagedara Jul 24 '20 at 08:37
one more question can i use any jquery with any jquery-ui or i do i have to use the latest version – m3sfit Jul 24 '20 at 08:39
some versions are compatible with other versions, i can't say it exactly. Better if you can use latest versions. – Eranga Gamagedara Jul 24 '20 at 08:41
