Is there a simple way to hide object header display from Dump()?

in General

I'm using Dump() to build a simple UI and would like it not to display the headers with the object information. What is the simplest way to do this?

This simple example

List<dynamic> list = new()
{
    new { A = "1", B = "xxx", Info = new { C = 1, D = "xxx", E = "xxx" } },
    new { A = "2", B = "xxx", Info = new { C = 2, D = "xxx", E = "xxx" } }
};

list.Dump();

displays as

but I would like it to display as

Is there a simple way to achieve that?

    And what will happen if user presses Alt+2? How tables which have no headers will be collapsed?

    If you are happy enough to remove all headers from everything that is dumped in your query, then you can call

    Util.RawHtml("<style>.typeheader {display: none}</style>").Dump();

    Note this even affects objects that are dumped before this line is called.

    Alt+2 behaves as you would expect, but Alt-1 may hide everything.

    If you only want to do this on one object, but are happy enough to remove headers on nested objects, then you could try

    Util.RawHtml("<style>.InvisibleTypeheader {display: none}</style>").Dump();
Util.RawHtml(Util.ToHtmlString(true, list).Replace("<td class=\"typeheader\"", "<td class=\"InvisibleTypeheader\"")).Dump();

    Thanks @sgmoore I'll give that a try.

    @i2van I'm not concerned about collapsing tables. It's a personal project and I will be the only user, which is why I wan't to use the standard Dump() functionality as much as possible rather than having to build my own UI as HTML.

    It works perfectly for my needs and using the second method I find that passing enableExtensions:false to ToHtmlString() disables Alt+1 and Alt+2 so I needn't worry about accidentally hitting those keystrokes.

    Thanks @sgmoore for this approach.

    I added the following to remove thead altogether for nested tables apart from tables with no summary (List) where column headers are still needed:

    Util.RawHtml("""
    <style>
        table table tr:has(> td.typeheader) {
            display: none;
        }
        table table thead:not(:has(th)) tr:has(> td.summary) {
            display: none;
        }
    </style>
    """).Dump();

    (not claiming css as my own...ai's very helpful)

    Indeed. Somewhere over the last year or two I have changed my mind about AI. I went from struggling to get anything useful from it to now being amazed and struggling to understand some of the things it comes up.

    Obviously yours is a better approach than mine, so it inspired me to ask AI if it could go further and hide most of the repeated column names headings.
    Then I asked it to see it could make all the nested table columns the same width and to hide the column totals.

    The script it produced is at https://share.linqpad.net/7lu8q2mq.linq (just don't ask me to explain it!)

    This is a screenshot of result with a demo using the TestWind database -

    Very nice. I can see these as a set of named profiles that could be applied from Util.
