===== Discussion =====
>This plugin messes up the Header levels causing them to nest/indent improperly. I've also come across situations where it caused the section edit buttons to be located improperly, and function improperly. Anyone know how to fix that? EDIT: the [[plugin:outdent]] plugin can help with the indenting problem (but not the section edit button problem). I suspect the plugin needs to be written to run BEFORE the rest of the syntax on the page is parsed.
>>To avoid this I use the [[include]] plugin as workaround:
>>The part of the wiki page that should be hided has to be moved to another page and then be included by %%{{page>...}}%%. Then the section edit function can be used in the included page.
>> --- [[user>Juergen_aus_Zuendorf|Juergen_aus_Zuendorf]] //2018-10-30 13:13//
>What's happen if someone show source of page ? do they see the hidden text ?
>> Yes they do. I should document that here.
>> There was [[http://ktyp.com/dev/doku/dokuwiki/hacks/hidephp|this patch]] for older version of DokuWiki to not show PHP code if user was not logged in. Would be a nice feature to register your plugin so that you cannot see the source between your tags. --- //[[otto@valjakko.net|Otto Vainio]] 2005-09-23 14:50//
>>> Sure wish email subscriptions were active for this page... --- //[[caylan@aero.und.edu|Caylan Larson]] 2005-10-05 17:13//
> I was hoping to use this plugin to hide rows in a table (so users would see a filtered selection of rows relevant to them). However the table gets broken at the point that the tags are inserted. Is there any way round this. I can see that the problem might be in the table code rather than anything you can tackle! I can of course hide the text inside each cell in the table that that will look pretty odd :-D --- //[[gjw@iqx.co.uk|Justin Willey]] 2006-06-10 21:00//
>> That __could__ be fixed by setting the sort number for the plugin lower than what table has. I cannot check this now. Will try next week. Or you can try it self also :-) --- //[[otto@valjakko.net|Otto Vainio]] 2006-06-10 13:19//
>>> Hi - Thanks for the suggestion, I tried that but it still seems to cause the table to be broken at that point, presumably something in the table rendering gets upset. --- //[[gjw@iqx.co.uk|Justin Willey]] 2006-06-27 12:12//
>>>>It does work if you hide the text in each cell separately, rather than the row as a whole. The table then suppresses the effectively blank row automatically. e.g.:
|1.1.2 |stuff, more stuff |
