I must say I do enjoy using Mobirise. Very easy and slick app.
Probably what most do, and not sure of help or not, however, this is what I do when cannot do things in Mobirise. I have used Mobirise for a number of one page sites and landing pages, and also with several email html, and had no choice but to use Dreamweaver to add bits in etc that where harder to undertake in Mobirise.
After designing in Mobirise and publishing to a folder. I just copied the whole lot of files into a new folder naming it maybe/ or whatever ... 'Mobirise DW adjusted'.
When wishing to do other items to that site in Mobirise, I completed in Mobirise new blocks or whatever and saved it as usual (published), then copied that Mobirise file itself (project) and pasted into the new one in the temp DW folder and replaced the one there. No need to copy the html pages, as they were already in the new mob DW adjusted folder.
then went into the html page I had added to or altered in Mobirise opened in DW, copied what had changed, and then just pasted into relevant section in DW (but can use any other software) just have this on machine and used to using). So that updated it completely and now... the new 'temp DW adjusted' folder is my final website folder.
Hope understandable, bit of a hassle, but only way could do it. I am not a coder but do understand html to a certain extent, and if there is a different way to do this when wishing to add lots coding would really like to know, as going into html and unlocking it for each block is not feasible when still w/o raking with blocks in a WYSIWYG way (which is so easy), so please would lover to know if a shorter way to do this. :)
