    <p>Sometimes when I'm working on a project I want to play around with some data. Often times the data is on one line and is huge (>25k characters). I understand I could <code>set nowrap</code> and have this line just run off the screen, but I tend to like <code>set wrap</code> for other reasons. So, as a workaround I want to hide these long lines in a marker fold (e.g. <code>{{{ long line }}}</code>). This works fine but I run into a problem with <code>synmaxcol</code> for some reason. If the folded line exceeds <code>synmaxcol</code> then when I open the file, the syntax highlighting runs over. For example:</p> <p><img src="https://i.stack.imgur.com/mXSCY.png" alt="enter image description here"></p> <p>However, as soon as I open the fold the syntax corrects itself:</p> <p><img src="https://i.stack.imgur.com/2CEab.png" alt="enter image description here"></p> <p>Having to open the fold every time is annoying though. As you can see in this example the line is not actually all that long -- it just exceeds <code>synmaxcol</code>. Since <code>synmaxcol</code> is exceeded at a "string" element, the rest of the file is highlighted as a string (so nothing but a singular double quote will stop it).</p> <p>Why is this happening and how can I fix it? I've tried this with different syntax files and filetypes and it still occurs. I've also tried it with no plugins, a minimal vimrc (containing only <code>syn on</code>) and a modeline to set <code>fdm=marker:synmaxcol=60</code> and it still happens.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
