Anyway, my main question is in relation to custom presets.
I'll try to explain better:
In fact, I do not want to create a custom preset from the beginning. I want to change the default preset that is already configured with some parameters and save as ...
Suppose you have a site with a base template common to some pages. I have a menu with 10 items that lead me to 10 areas of the site with content with some differences in layout. All these areas have the base layout of my preset default. Only need to create another 10 custom presets based on this default with minor modifications.
At the template configuration, select the menu item you want, change those parameters that are different from my default and SAVE these settings as a custom preset.
I see that if I create one from the Beginning, I can save and apply in a specific menu item. But if other custom presets that I need, requiring only a few changes, it makes sense I have to create another one from the Beginning.
In fact, I do not see what sense is because the custom preset save button does not appear when I am editing a custom menu item.
all the presets you have in your site (default presets and the custom presets you have already created) can be selected under DEFAULT settings.
for example...
there is a preset called preset1, which is selected as the default preset.
there is a preset called preset2, which is almost the preset that you want to use on your menu item called "contact" but with a different link color for example.
in the default settings you select preset2, then change the link color, then click "save custom preset as new" and call it ana1.
then you "CLOSE" the template parameters (do NOT use save or apply)...
then you reopen the template parameters...
then you click "MENU ITEMS" > "CONTACT"... and select the new preset ana1.
then click SAVE or APPLY.
the default preset for your whole site will be preset1, the preset on the CONTACT page will be ana1.
now you have another page called ABOUT US...
you want to create a new custom preset which is very similar to ana1. you want to call it ana2.
here is how you do it:
open your template parameters.
you will see that preset1 is the default preset.
under the DEFAULT settings you select ana1.
then you change the settings for ana1, for example you use a different link color, then click "save custom preset as new" and call it ana2.
then you "CLOSE" the template parameters (do NOT use save or apply)...
then you reopen the template parameters...
then you click "MENU ITEMS" > "ABOUT US"... and select the new preset ana2.
then click SAVE or APPLY.
the default preset for your whole site will be preset1, the preset on the CONTACT page will be ana1, the preset on the ABOUT US page will be ana2.
you can do the same with all presets, THERE IS NO NEED TO CREATE THE ANA2 PRESET ON THE CONTACT PAGE THAT HAS ANA1 PRESET ASSIGNED TO IT. YOU CAN CREATE THE ANA2 PRESET ON THE DEFAULTS PAGE.
