Hello @Li78,
JMP does not provide that functionality, but the JMP Live team is looking into enhancing the organization of published reports.
If you would like to see this capability in JMP, please enter a suggestion on the JMP Wish List.
If you are familiar with web page development and would like to build a page something like the JMP HTML5 Examples page, you could copy a web report's index file (index.html) to a folder above several web report folders and edit it with a standard text editor to replace the images and hyperlinks to refer to the index files in each sub folder.
Here's an example with two web reports in folders wr1 and wr2:
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" href="wr1/_css/jmp-reports.css">
<title id="j-webreport-index-title">Two Web Reports</title>
</head>
<body>
<div id="content" class="group">
<div class="section_header">
<div class="title_header">
<h1><a href="" target="_top"><img src="wr1/_logo/logo1.png" alt="logo"></a> Two Web Reports</h1>
</div>
<h2 id="j-webreport-index-description"></h2>
</div>
<div class="section">
<div id="report-rack" >
<ul>
<div class="item j-webreport-item" id="item-0">
<li>
<a class="j-item-url" href="wr1/index.html" target="_top">
<span id="rack-0"><img class="j-item-thumbnail" src="wr1/_images/Big_Class_-_Bivariate_of_weight_by_height_4_thumb1.png" alt=""></span>
<p class="timestamp">03/03/2022 1:40 PM</p>
<h3 class="j-item-title">Web Report 1</h3>
<p class="j-item-description"></p>
</a>
</li>
</div>
<div class="item j-webreport-item" id="item-1">
<li>
<a class="j-item-url" href="wr2/index.html" target="_top">
<span id="rack-1"><img class="j-item-thumbnail" src="wr2/_images/Big_Class_-_Graph_Builder_thumb1.png" alt=""></span>
<p class="timestamp">03/03/2022 1:40 PM</p>
<h3 class="j-item-title">Web Report 1</h3>
<p class="j-item-description"></p>
</a>
</li>
</div>
</ul>
</div>
</div>
</div>
</body>
</html>
Notice how the css style file from the first folder is used: wr1/_css/jmp-reports.css. Also, thumbnail images representing each group are picked from the wr1/_html and wr2/_html subfolders.
The top level page will look like this:
I hope this helps.
