Unfortunately in all websitex5 versions untill now, in the "Pages" Creation section, when we add a "Text" part at the page, we are not able to write english and arabic words in a line together in a correct position inside.

for example :

ما قصد خواندن یک کتاب به نام murder داریم

you can see clearly that for the languages which start from the right side, its impossible to write the english words inside the line with arabic words together at the correct position.

i have attached the correct sentence.

Iwill be pleased if you take a look at microsoft office porgrams like "Microsoft Word" to learn how microsoft have solved this problem and you solve it in the next versions too.
